Options menu updates for 6.2

I updated all of the new *Options* menus throughout the chapters that had been updated for 6.2. All old portlet title bars and Control Panel *Options* buttons (originally wrench icons) should now be up-to-date.

I also threw in a commit updating the structure editor snapshots. The icons were updated in the product a few days ago, which were blocking the image updates.
